| 摘 要： | 泥石流是北京市山区的主要地质灾害类型之一，文章将北京市以3km×3km的网格进行剖分，选取地形、地层岩性、构造、灾害因子及降水5个因素作为泥石流危险度区划的指标，基于GIS对北京市泥石流危险程度进行了区划。其结果可为北京市开展泥石流预警预报、减灾防灾规划和山区经济建设布局等提供科学参考依据。

| Abstract: | Debris flow is the heaviest disasters in the mountainous area of Beijing. The Beijing Region was divided by 3km × 3km gridding in this research, and the terrain, stratum, geological structure, disaster and precipitation were selected as the basic indexes in the study of risk factors zoning of debris flow. Based on the GIS software, the risk factors zoning of debris was divided into five ranks. The result of this research can be a scientific reference to the forecast of debris flow, programming of disaster prevention, and the development of mountainous economy in Beijing. |
